Results:
The licensee was in the forty-fif th day uf the outage as of October 31, 1988, and are within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the schedule. Appar-ently the efforts spent on scheduling before the outage have contri-buted to the ability of staying on schedule at this time.
Of over 300 environmental qualification tasks scheduled during the outage, 133 have been completed.
Over 11,000 tasks were scheduled and approximately 6,000 have been completed SG ecidy current testing has been completed with on going plugging operations and tube pulling completed.
Outage radioactivity exposure has been controlled very well with the large amount of steam generator work taking place. The exposure is at 317 person-rems.
Emergency DG "A" wo k was slow due to leaking water jacket seals.
However, the diesel was operational on time.
Diesel Generctor "B",
"B" train work such as SW, CCS, reactor building spray pump and sump suction, and "B" train RHRS work is in progress. Critical path work on the schedule centers around "B" train work and reloading of fuel that began October 30, 1988.
Within the areas inspected, no violations or deviations were identi-fied.
